For a single-phase motor of 2 HP rating, supply voltage is 240 V ac. If the efficiency is 70% and power factor is 0.8, find the input current. · 19.95 A · 15.95 A 

Motor. Model. Prefix. Nameplate Rating. Full. Load watts. Line to Line (1) Amps. Circuit Breakers or Fuse Amps. Typical Submersible. kW. HP.

7/20 · 1 Hp = 0.746 kW After that use the formula kW to ampere : For 3 phase power supply ; kW = I x V x 1.732 x pf For 1 phase power supply ; kW = I x V x pf Example :- 1 unit induction motor power rated 25 hp,200 VAC,3 phase,90 % power factor,calculated the full load ampere. Calculation :- kW = 25 hp x 0.746 kW = 18.65 kW = I x V x 1.732 x pf

Calculate the rated required capacitance value for the single-phase, 220V, 1 HP, 50Hz, 80% of the motor. 1 HP = 746 Watts. Use our capacitance calculation formula. C (µF) = 746 x 80 x 1000 / (220 x 220 x 50) = 24.66 µF. Hence 1 HP Motor required 24.66 µF capacitance to start the motor smoothly. But in the market, you can get 25 µF.

For example a 1.5 HP Baldor motor turning 3450 rpm draws 13.4 amps on 120 volt service. A Leeson brand motor of the same specification list 12.4

2022/3/11 · Motor starting current or locked-rotor current relies on motor design. In NEMA motor design, locked-rotor current specify by design letter (i.e. B, C and D etc.) and voltage level. If a motor complies with IEC 60034, starting current shall be: SC/FLC = 7 for LV motors SC/FLC = 5 for HV motors Motor rating again mechanical load
